Hi,
    I am using ojb1.0_rc4, ODMG api with OJB queries and mysql4.
    When running OJB queries using the broker, is it necessary to begin, commit or 
abort the broker transaction?
    Which one should I use? Example 1 or 2?
hmm, if you start an odmg-transaction and obtain a PB instance via
PersistenceBroker broker = ((HasBroker) transaction).getBroker();
I would recommend not to do any PB-transaction action. So 2)
should be ok, because you only do read-operations.

    1) 
        ...
        PersistenceBroker broker = ((HasBroker) transaction).getBroker();
        broker.beginTransaction();
        Iterator it=broker.getIteratorByQuery(q);   
        //do something with the iterator
        broker.commitTransaction();        
        ...

    2)
        ....
        PersistenceBroker broker = ((HasBroker) transaction).getBroker();
        Iterator it=broker.getIteratorByQuery(q);
        //do something with the iterator
        ....
Thanks,
